Measurement Computing's PCI-DIO24/LP is a 24-bit, logic level digital I/O board for low profile/half height PCI bus compatible computers. The board is compatible with both 5 V and 3.3 V PCI buses.
The PCI-DIO24/LP is based on the industry standard 82C55 chip, and the 82C55 I/O pins are brought directly to the board's I/O connector. The 82C55 is a powerful 24 bit chip and functions as two 8-bit ports, (Ports A and B) and a third 8-bit port (Port C) that may be further divided into two 4-bit ports (Port C-HI and C-LO). The CMOS outputs of the 82C55 are suitable for driving a wide array of logic devices, though the chips ±2.5 mA drive capability may not be enough in some applications.
Connections to the PCI-DIO24/LP are made through a DB68, ultra-micro SCSI type connector. The board uses the C68MMS-x series cable and the CIO-MINI68 screw terminal board.
The PCI-DIO24/LP is completely plug-and-play. There are no switches, or jumpers on the board. All board addresses, interrupt channels etc. are set by your computers plug-and-play software.
"When we started designing these systems, we needed to locate a robust data acquisition unit that we could trust, have multiple inputs and a simple but effective software interface and a reasonable price." Michael Gray, Precia Molen
"We have used MCC devices for many years on any number of different projects, from pile testing to seismic tests, and we've always been more than satisified with their performance. This was the natural choice for us." Stephen Kemp, Manager, GBG Structural Services
